An image processing apparatus including a processor comprising hardware. The processor being configured to: divide an imaging signal that is obtained by capturing an image of an inside of a subject into a first base component and a detail component, the first base component corresponding to an illumination component of an object, the detail component corresponding to a reflectance component of the object; generate a second base component by performing a color enhancement process on the first base component for increasing color gradation in a predetermined color space; and synthesize the second base component and the detail component to output a synthesized signal. Where the color enhancement process is an enhancement processing on the first base component for extending a color distribution range of at least one component of an L component, an a component, and a b component in a Lab color space.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image processing apparatus according to claim 1, wherein the processor is further configured to perform an enhancement process on the a component for extending a color distribution range.
5. The image processing apparatus according to claim 1, wherein the processor is further configured to perform a second enhancement process on the b component for extending a color distribution range.
8. The image processing apparatus according to claim 7, wherein the processor is further configured to perform an enhancement process on the a component for extending a color distribution range.
10. The image processing apparatus according to claim 7, wherein the processor is further configured to perform a second enhancement process on the b component for extending a color distribution range.
